The Messenger of Allah ﷺ as saying: If anyone has property given him in life-tenancy for the use of himself and his descendants, it belongs to the one to whom it is given and does not return to the one who gave it, because he gave a gift which may be inherited.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ أَيُّمَا رَجُلٍ أُعْمِرَ عُمْرَى لَهُ وَلِعَقِبِهِ فَإِنَّهَا لِلَّذِي يُعْطَاهَا لاَ تَرْجِعُ إِلَى الَّذِي أَعْطَاهَا لأَنَّهُ أَعْطَى عَطَاءً وَقَعَتْ فِيهِ الْمَوَارِيثُ  

A similar tradition has been transmitted by 'Aqil from Ibn Shihab and by Yazid b. Abi Habib from Shihab. Al-Auza'i's wordings vary from those of Ibn Shihab. Fulaih b. Sulaiman also narrated the tradition like that of Malik.  

عَنِ ابْنِ شِهَابٍ وَرَوَاهُ فُلَيْحُ بْنُ سُلَيْمَانَ مِثْلَ حَدِيثِ مَالِكٍ  

The life-tenancy which the Messenger of Allah ﷺ allowed was only that one should say: It is for you and your descendants. When he says: It is yours as long as you live, it returns to its owner.  

إِنَّمَا الْعُمْرَى الَّتِي أَجَازَهَا رَسُولُ اللَّهِ ﷺ أَنْ يَقُولَ هِيَ لَكَ وَلِعَقِبِكَ فَأَمَّا إِذَا قَالَ هِيَ لَكَ مَا عِشْتَ فَإِنَّهَا تَرْجِعُ إِلَى صَاحِبِهَا  

The Prophet ﷺ said: Do not give property to go to the survivor and do not give life-tenancy. If anyone is given something to the survivor or given life-tenancy, it goes to his heirs.  

أَنَّ النَّبِيَّ ﷺ قَالَ لاَ تُرْقِبُوا وَلاَ تُعْمِرُوا فَمَنْ أُرْقِبَ شَيْئًا أَوْ أُعُمِرَهُ فَهُوَ لِوَرَثَتِهِ  

The Messenger of Allah ﷺ decided a case of a woman from the Ansar to whom an orchard of date-palms was given by her son. She then died. Her son said: I gave it to her for her life, and she has brothers. Thereupon the Messenger of Allah ﷺ said: It belongs to her during her life and after death. He then said: I gave a sadaqah (charity to her. He replied: It is more unexpected from you.  

قَضَى رَسُولُ اللَّهِ ﷺ فِي امْرَأَةٍ مِنَ الأَنْصَارِ أَعْطَاهَا ابْنُهَا حَدِيقَةً مِنْ نَخْلٍ فَمَاتَتْ فَقَالَ ابْنُهَا إِنَّمَا أَعْطَيْتُهَا حَيَاتَهَا وَلَهُ إِخْوَةٌ فَقَالَ رَسُولُ اللَّهِ ﷺ هِيَ لَهَا حَيَاتَهَا وَمَوْتَهَا قَالَ كُنْتُ تَصَدَّقْتُ بِهَا عَلَيْهَا قَالَ ذَلِكَ أَبْعَدُ لَكَ
